"The two main challenges for mobile food vendors are permits and costs, Broad Leib said.

'In a lot of cities, mobile vendors are not allowed,' she said. A permit for operating a produce cart simply doesn’t exist and the majority of people don’t know how to apply for a variance. Cities that streamline the permitting process and reduce permit fees will reap the benefits of mobile food vendors, she added.

'Ultimately we want residents to use the mobile food vendors. Cities need to make it so they can operate affordably,' Broad Leib said."
